I paid my Lightroom but it says that my subscription is expired

I fixed mine showing the same symptoms by uninstalling Lightroom specifically and installing it back.

Not sure if your case is the same as mine but worth mentioning that on my iPad the Creative Cloud and Photoshop apps both looked fine and my Lightroom was working okay on the MacBook Air. For some reason the Ligthroom app wasn't communicating properly with their servers and a simple reinstall fixed it.

Good luck !

Same issue here Deborah , though mine seems to be working fine on the macbook air , weirdly.
I've looked for related conversations here and it seems to be a recurring problem, there are some posts reported years back with the same symptoms.

I am keeping my fingers crossed as I don't have a lot of time to edit my stack and I'm already behind because of this issue now.
